ndisplay with inputreplication ue5.2

Hello,
i am trying to use ndisplay with the ue5.2. I activated the “follow local player camera” and the pc with the keyboard and mouse moves around but the other clusters stay at the same position. Is there something i forgot to activate for the inputreplication? In the old version i added a line in the cfg to replicate the inputs.
At the moment i don’t use the quadro sync 2 boards for synchronisation. Can they share the position too? The Documentation is a little bit confusing.
I already tried to add the ndisplay sync parent to the default view point in the ndc_basic but it does’nt worked.
Someone can help me please?

Solved.
At Replication was a variable called ReplicateMaster but now it’s called ReplicatePrimary.

Hi dude, I just want to ask why I use the switchboard to run the nDisplay node, the Mouse click and Keyboard input is not working?
